To all whom/ it may concern Be it known that I, RANsoM E. RATHBUN, a citizen of the United States, residing at Sioux City, in the county of Woodbury and State of Iowa, have invented a new and useiul Spnngfiuslnon Tire, of Wine the follow I 7V invention relates to the wheels of ve- *ifiibw, and has for its-object the rovisien e spring-cushion for the tire o :yliliCi'i wiiiffbe ebie to support any desised load and. st the same time furnish the required elasticity.

The invem'ion is especially-adapted for eutoinobiles, owin to its strength, eheepiiess, a-ihii durebilit out may be applied to any kind of vehic e.

invention consists in, the novelty of construction ;combination, and arrangement of parts, as Will be pointed out more definitely in the claims. In the drew isms, Figure 1 is at side View of e wheel to Wh le my invention is attached. Fig. 2 is the same View witiitiie shields removed. Fig 3 is a plan View of the same.

Referring now to the illustration, in which like parts are designated by similar letters'of reference, Aisthe hub of the Wheel, and B B thes okes.

C 18 the folly, and D a rim of steei or other leaving a spsee between. The sides of severed by shields E, secured. to the outer rim by meims of the bolts F, which pass through the bloelisG. (Ether ooits Fsecure the shields together, pessiii inside the feii v At segulzii intervals in the sps'oebetween the ieiy end the fill site the ex of spoke, the rim is pro ideai with blocks G, 'projeeting towerol, but not 'ng, the feiiy. Between each of the bio'oiz's spiiiigs 1, e215 J are secured to the fatty the miciclie of the springs by means boits K, Whieh hold the Inidciie part of the springs ifimly zponthe felly. The s rings are all concave iromthe. side toward ti -is Tim, the springs H extending iaetween the blocks, the swings i being somewhat shorter, with the en s cursing outward. toward the rim,iwhile the sp 'mg's J are the shortest of e21,
